The recent training regime advice from Grimes, given as part of Adidas’s training campaign, includes some comments about experimental surgery to eliminate blue light. Whilst we absolutely respect any person’s choice to try new or alternative treatments, the comments, which have been received as health advice have caused some confusion. Firstly, it is very important that you do not try to perform eye surgery yourself. If you have concerns about depression, we recommend you seek advice from a registered councillor or your GP in the first instance. If you are concerned about the effects of blue-light, on your eye health and sight, we recommend you speak with your optometrist for advice.

There have been various claims made about blue light, with regards to seasonal affective disorder. A recent gold standard Cochrane review concluded that here is little evidence overall that light therapy is useful for treating seasonal affective disorder. Separately, there have been various claims made about blue light and long-term eye health, but using blue light–filtering eye implants to impart health benefits to the eye is currently not supported by the best available clinical research evidence.

If Grimes did have a blue-blocking, orange coloured filter implanted into her eye, the surgery is not supported by scientific evidence.
